Replacement for obsolete components: Obsolete NPN Transistor BC817K from Infineon now from Diotec - available at Rutronik

created by Emilia Mance | 04/24/2018 Knowledge

The NPN Silicon AF Transistor BC817K from Diotec in a SOT-23 package is an equivalent substitute for the obsolete BC817K from Infineon.

With a power dissipation of 500mW, a high collector current of 500mA, a peak collector current of up to 1A as well as a high current gain between 100 (BC817K-16) and 630 (BC817K-40), measured at 100mA, the BC817K is ideal for all general AF applications.

The surface mount transistor has a low collector-emitter saturation voltage of 0,7V, measured with pulses of 300µs and a duty cycle below 2%. Its SOT-23 plastic case is RoHS compliant.
